Last June, Mayor Bloomberg and Randall Stephenson, AT&T's CEO, announced a five-year initiative to provide free WiFi in over two dozen NYC park locations. AT&T, not taxpayers, pays for the installation and maintenance.

Since then, WiFi is up and running in the areas listed below (with more to come). We checked several locations and the service—for which no sign-in or password is needed—seems to be working well. At the bottom, we've also included additional park and outdoor public space with free WiFi that's not part of the AT&T initiative.
